11287: Set Your Computer to Display All File Name Extensions (CWU)

CWU: A state W2 e-file upload is being rejected by the state because of a missing file name extension.

File name extensions required by state specifications are programmed into CWU. If your computer is set not to display all file extensions, however, the .TXT and .CSV extensions are not available and a state file that requires an extension may be rejected.

To display all file name extensions, there is a global Windows folder option that you must adjust. Follow the instructions below for your Windows operating system.
